. Specification of Letters Patent. Patented Sept. 13, 1910.

Application led March 5, 1909. Serial'No. 481,416.

To all whom it may concern.'

Be .it knoivn that I, STANLEY lV. LYMAN, a native-born citizen of the UnitedStates, i

residing at Roberts, in the county of Carbon i and .State of Montana, have invented new and useful Improvements in Road-Bedsl of which the following is a specification.

The invention relates to anmprovenient in road hed structures for railroads, and is particolari-lyY directed to a concrete or other Figure 1 is a plan view of a road bed constructed in accordance With my invention. Fig. -2 is a detail perspective of one ol the metallic structures or boxes. Fig. 3 is a 'section on line of Fig. 1. Fig'. 4 is a `section on line 4--1 of Fig. 1.

Referring to the drawings, my improved road bed comprises in addition to the material forming the composite portion of the structure a series of metallic structures or boxes A designed to be' respectively arranged at the opposing ends of each cross tie of the road bed. These boxes are of identical structure and are in' effectv molding boxes for receiving and forming a -portion of the` composite material and` permitting the use of ordinary elements for the'forming of the remaindervof said material.-

- The detailed structure of theboxes is more particularly shownin Fig.` 2,vl from which it will be seen to vcomprise side-Walls 1 and 2, and end wallsB and 4, the side wall l being designed to form the outer end of the cross tie and for this purpose is preferably solid, the remaining side Wall and the end Walls being of skeleton formation to I. permit the 'disposition of `the composite material through said Walls to prov1de an integral Structure.

cand alloWer bar 15.

formed With nturned anges 5 and on the inner surface immediately in rear of the terminals of'said flanges With vertically extending ribs 6, said ribs and flanges forming sockets 7 on the inner surface of the Wall 1. The side Wall 2 is of skeleton form including the top and bottom bars 8 and 9 and side bars 10, said .latter bars extending across the end edges of the bars 8 and 9 and projecting beyond the respective surfaces of said bars. The inner edge of each side bar 10, or that edge next the wall 1, is formed with an inwardly projecting flange 11, extended in parallel relation with the bars S and 9 and, together with a rib 12, extending throughout the height of the wall innnediately in rear of the terminal of tlie iange 11, forming a socket 13 corresponding to and arranged directly opposite the flange 7- of the Wall l.

The end walls 3 and 4 ,are of identical structure, each including an upper bar 11 The res ective upper and lower bars of the end Wa ls are spaced apart a distance equal to the spacing of the bars 8 and 9 of .the side Wall 2, so that an uninterrupted opening is provided in the respective walls except the outer side Wall 1. The upper and lower bars of each end Wall are connected at their edges by vertically arranged forwardly extending flanges 16 and 17 adapted to snugly tit Within andl throughout the lengths .of the respective recesses 7 and 13, so that the end Walls are arranged for slidable connection with the side Walls inassembling the box. The upper bar 14 of each end .Wall is formed with an outwardly extending projection 18, in the forml 'of a supporting flange, which at its central point 'is depressed to provide a V- shaped socket 19 for a purpose which will presently appear.' The upper'bars 14 of' the end Walls are preferably of\V-shape` in side elevation to provide the necessary .strength of material op osin the sockets 19. flanges 18 are o less ength than the bars 14, terminating in spaced relation with the proximate surfaces'ofV the flanges 5 and l1,Whe re` by sockets 20 are provided at each end of each bar 14, for a purpose which Will resently appear. The relatively outer sur aces of the 4bars 8 and 910i? the side Wall 2 are provided' with ribs21 extending throughout the height of the wall and in spaced parallel relationj-to .that portion of the end ba'r-s 10 projectingbeyond .the outer surface of the The bars 8 and 9, whereby sockets 22 are formed for a purpose which will presently appear.

The relativelyupper edge of the side Wall 1 and the upper edge of the'bar 8 of the side wall 2 are formed with alined notches 23 to receive a4 rail holding member hereinafter" to be described.

The bars 14 of the with a series of apertures 24,' the bars 15v being formed with similar apertures 25.. The bars 8 and 9 of the side Wall 2 are' `formed with ,apertures 26 and 27 respectively, said apertures serving to tie theboxes together in theformation of the road bed, as Will presently appear. The res ective boxes are arranged in series longitudlnally of the road bed, being disposed 'so as to present opposing pairs at the points to be occupied bythe cross ties. rThe longitudinal series of boxes are tied in their respective positions by tie Wires 28 and' 29., which extend longitudinallyof the box and diagonally therefrom to the adjacent box, that is, vone series of Wires Will be passed through the alined apertures.. of they upper bars 14 of one and then projected diagonally of the next 'adjacent box and 4through the alined apertures,

fof theloWer bars 15, being, of course,

ertured bar 8 of said box and transverse the structure -to and through the projected from these bars upwardly to and lagonally aperturesof the bar of the lirst mentioned box and upwardly Within said box and 'con-1 nected to the 'Wire terminal Within said box. Thetiegwires which may be in any number arejA thusetfective for tying the boxes in fixed relation longitudinally and .transversely of the road bed. 'l/Vith -the'looxes thus assembled the form or molding frame of the road' -bedis completed by board or partition structures Which are inserted in the alined recesses 22 oi the opposing boxes and in the alined 'recesses 20 ofthe successive boxes. These respective. recesses support thepartition invparallel relation to formin eiiect sides of mold boxes extending ,longitudinallyand transversely of the road bed. i The form thus presented is then lilledwith the composite mixture as concrete,'the same being securely tamped in place. AIn connection With `such of the boxes, as usethe rail tie member hereinafter described, I provide a supporting meuibeil, preferably a' strip'of metal having in its bottom Wall ata point intermediate its ends an inclined portion 32 oifsetting the respectiveends of the strip'.

end .Walls are formedv `The ends of the lbott-om are bent to'provide tacle in Which the rail tie members are in serted and Which serves to prevent encroachment of the concrete filling on said rail tie members. The rail tie members are thus supported to permit their normal operation when desired Without interfrencewrom the concrete filling.

In conjunction with the road bed I use a railrstructure, which is more particularly described and claimed ina copending application. VAs a part of the rail structure I includea baise or chair member 34 'which is or' approximately V-shape in .ci-oss'seotion, the lower inclined surfaces of which are shaped to fit the depression 19 in the end Walls of the box. To further secure the rail in place I provide holding clamps 35 adapted to be secured to the box by bolts passing through theiclamps and throughY openings 36 formed l in and adjacent each end of theliiange 18 of the end Walls, as clearly shown in Figs. 1 and 3.

At determinate points throughout the lengths of the road bed, and preferably overn l ino` certain of the ties l, Jrovide a rail ftie member'including u. neutral coupling 3i" formed with an angular body 38 for the application of a wrench or other operating member and having sleeves 39 projectingl fromsaid member. riorl'y threaded for the reception oit tubular members 40, which at their ends are pro vided. with blocks 4l formed on their rela-v tivelyV outer edges with an overhanging lip 42. Clamp rods 43 extend rthrough members 40 and are threaded 1n a bore of the 'body 38 of the coupling, the ends of said The sleeves are intei rods projecting beyond blocks 4.1 and hav ing hook ends 44 to coperate with the overhanging lips 42 of the blocks to engage the rail. In the road bed structure the rail tie is-secured in place by a yoke 45 loosely en gaging the sleeve extensions .J7 of the coupling' and having its depending arm 46 formed with a terminal eyeto `receive a rod 47 passed longitudinally through Vthe tie structure and through the end Walls l of the boxes forming the terminal'sof theparticw lar tie structure, securing nuts 48 fixing the parts in applied position. In their passage through the blocks 41 the rods 43ers' prefer-V ably squared in cross section and tit similarly formed apertures in lsaid blocks, Whereby the rotation of-the coupling will adjust said rods with relation toeach other Without permittin a revolution offthe rods to interfere with t e proper position of the hooks 44.

The road bedb thus constructed is an integral. composite structure throughout, the

eeaaee rails being directlysup'p'orted by longitudi'- nal members of Stringer type extending the.

full length of the road bed and connected atk appropriate intervals by cross ties, the lon gitudinal stringers at the junetures of the cross ties therewith bein reinforced by metallic lboxes which throng out the entire road .1 ber.

bed are interconnected to prevent independent movement of said boxes and also to provide a reinforce for the composite structure between the boxes. l

If desired the'concrete reinforce maybe Vin part substituted by. Wood in order to increase .the resiliency of the supporting mem- Having thus described the invention-What l.
